Leopard geckos are naturally hunters, and rarely accept 'canned' foods- any food that is not moving around.
I too detest working with crickets. I still feed plenty of crickets but prefer to feed mealworms with are also nutricious, much easier to work with, can be kept much longer than crickets, and do not nearly small as bad. Do you have an opposition to mealworms?
If you are looking for a similar reptile to keep that does not require live insects at all, consider crested geckos. They are about the same size as leopards, do not require any special lighting or heating setup, and eat a powdered food mixed with water.
